Geometry Center

<h2 id="geomview">Geomview</h2>
<p>Much of the work done at the center was for the development of Geomview, a three-dimensional <a href="/facts/Interactive_geometry_software/QJgHTbyd">interactive geometry program</a>. This focused on mathematical visualization with options to allow <a href="/facts/Hyperbolic_space/kI7tnwdk">hyperbolic space</a> to be visualised. It was originally written for <a href="/facts/Silicon_Graphics/DKvkrfLX">Silicon Graphics</a> workstations, and has been ported to run on <a href="/facts/Linux/9FvCKSTq">Linux</a> systems; it is available for installation in most Linux distributions through the package management system. <i>Geomview</i> can run under <a href="/facts/Microsoft_Windows/bwhAhuSL">Windows</a> using <a href="/facts/Cygwin/0ANCmAgH">Cygwin</a> and under <a href="/facts/Mac_OS_X/Y93vVpTm">Mac OS X</a>.
</p><p>Geomview is built on the Object Oriented Graphics Library (OOGL). The displayed scene and the attributes of the objects in it may be manipulated by the graphical command language (GCL) of Geomview. Geomview may be set as a default 3-D viewer for <a href="/facts/Mathematica/dRwoGFG2">Mathematica</a>.<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a>

<h2 id="videos">Videos</h2>
<p><i>Geomview</i> was used in the construction of mathematical movies including:
</p>
<ul><li><i><a href="/facts/Not_Knot/UMHDCrg7">Not Knot</a></i>, exploring hyperbolic space rendering of <a href="/facts/Knot_theory/mb7rtqVP">knot</a> complements.</li>
<li><i>Outside In</i>, a movie about <a href="/facts/Sphere_eversion/6PAcGw71">sphere eversion</a>.</li>
<li><i>The Shape of Space</i>, exploring possible three-dimensional spaces.</li></ul>
<h2 id="other-software">Other software</h2>
<p>Other notable software developed at the Center included:
</p>
<ul><li><i><a href="/facts/Surface_Evolver/Ub6cGCRl">Surface Evolver</a></i>, to explore <a href="/facts/Minimal_surface/Fy7VkrLQ">minimal surfaces</a>.</li>
<li><i><a href="/facts/SnapPea/hx3QbENv">SnapPea</a></i>, a <a href="/facts/Hyperbolic_3-manifold/U8AAYhsw">hyperbolic 3-manifold</a> analyzer.</li></ul>
<h2 id="website">Website</h2>
<p>Richard McGehee, the center's director, has stated that the website was one of the first one hundred websites ever published.<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a>
